catalase and glutathione supplements Antioxidant enzymes. CAT: catalase; GPX: peroxidase; GR: Reduced Glutathione

Bottom line: Glutathione is a vital component of hormonal and metabolic health

CYP24A1, a gene that provides instructions for making the enzyme 24-hydroxylase, is involved in the catabolism of both 25(OH)VD 3 and 1,25(OH) 2 D 3, thereby limiting vitamin D receptor (VDR)/1,25(OH) 2 D 3 signaling 14

Furthermore, constant 1/ 2 values for all E170X mutants (in contrast to K105X mutants) suggest that the mutation of Glu170 had no effect on a rate-limiting reduction by GSH (Fig
